Lupe has also been acting erratically in Chicago lately. After getting into a Twitter beef with Chief Keef, he threatened to quit the music business. And last week, he announced he’d scrapped plans to release a follow-up to his popular "Food & Liquor" album.

Hypervocal, one of the party’s sponsors, Tweeted after the show that it was “Disappointed that an artist took opportunity to use an event celebrating innovation/startups to make a political statement.”

I’m sure Hypervocal would not have been disappointed if Lupe had made a political statement by singing Obama’s praises. But they should have known who they were hiring before they invited him to the party. I’m sure they thought Chicago + rapper=Obama fan. That may be the case with Common, Rhymefest, Twista and Kid Sister, but it’s not the case with Lupe.
